RAM issue - sad but true


Flowy
 Share

Question

Winter has gone and 30 degrees are back in town so time ago I stopped all scenes that control the heating system in the house.

We are talking about 16 scenes changed from automatic to manual, but I did not stop the automatic daily restart scene.

Immediately after that, the used RAM dropped from 99% to 80%.

Now, looking at the RAM usage I can read numbers between 96 and 99% without implementing anything new.

Yes it eats RAM, a lot, not known why, not possible to do anything about that.

I read that people with FW 4.130 are less happy then 4.120 or 4.110 or xxxxx.

Guys nothing changed, it's always the same story.

Don't think that a new FW is totally rewritten from zero every time and in the correct way, it is just a bunch of extra coding squeezed inside the other rows of code.

Hardware remains the same.

Issues remain the same.

Sad but true (cit.)

RAM usage is a mix of Buffer, Used Space and Cache.

It's no problem if their overall consumption is high.
It's only serious if Used Space takes up almost any space.

to be honest, ram cache <> free ram

you can call it what you want but it isn't

    not correct,

    whatever use you do with the RAM it is NOT a free RAM

    that is an old known story and the obvious effect is.....frozen

    What I meant was that if the system has access to a lot of buffer or cache memory, there are no major problems because they can be returned to the system if used space requires more memory.
    It is only when all memory is occupied by used space as it becomes critical.

    that's is the reason why it is a not correct assumption

    You are sure only about what stated as free RAM.

    All the rest is occupied and managed by the software and if the SW is buggy then you do not have RAM.

    More than that there is a huge difference between possibility to be accessed and managed by the OS or by the SW.

    And as always said here in the forum topics, at the end of the day the HCL could freeze multiple times a day and the known reason is the RAM utilization.
